How did the Purewave work for your NLOS customers versus Cambium PMP100
gear?

So what are people using to replace their 3.65 WiMAX equipment like
Cambium 320 and Purewave/Mercury? Is Bai Cells the answer? In any
case, it seems like a forklift upgrade. I would like to say some
other frequency band, but what? If not 900 MHz, it seems there is no
unlicensed band that can do what we need.
My original trip down the WiMAX rabbit hole was actually intended to
be a preliminary step toward licensed 2.5 GHz, until I found out that
was not feasible for us. But now I’ve got a lonely Purewave
basestation that I don’t want to add customers to, I don’t think the
latest Mercury help, and I don’t know what to do with the existing
customers. Some are LOS so maybe the NLOS subs just need to go bye-bye?
We are using Cambium 450 in 3.65 GHz and it is working out great for
us as a 2.4 GHz replacement, but only for LOS or through a tree or
two. Can’t afford low modulation clients <4X.

one of the documents i was reading said 20% throughput loss from
extended range, thats what i was asking about real word experience
from, 320 documentation across the board was always questionable.
I would love to not use it, but 320 was the (dont start the
penetration argument) only thing at distance we could pick customers
up through foliage to get them off 2.4fhss, even 900mhz wouldnt work,
I assumed it was wimax and multipath that allowed it to happen

See attached link budget sheet. Back in the day, 5%-8% capacity
loss was the number thrown around with extended range enabled.
IMO, disable extended range and deny those distance subs. You'll
increase your overall capacity as a result.

at 10mhz we get 40 eirp correct?
Anyone using the extended range know how much real world
sector capacity loss we have? is the aggregate with loss on
10mhz going to be less than the throughput at 7mhz?

Yes, but there is an extended range config parameter that
overcomes that limitation.

at 10 mhz isnt the max distance dramatically limited
over 7mhz?

We do it like this...
A = 3655
B = 3682
C = 3669
D = 3695
It'll give you at least 1mhz separation between
sectors (which is required).

Can the Cambium 320 radios operate in ABCD
fashion (10 Mhz channels using covering from
3650 to 3700) with 4 Cambium sectors? I know
AABB with splitters is common and we did some
that way, but we had to remove splitters to
get extra gain in some areas.
I seem to recall there was some “edge issues”
or something like that?? We always lock the
customer down to a given
frequency/basestation, for what that’s worth.
